: 'My invention relates to improvements in cable hangers and more; especially to a type cmbodyinga flexible strap element which is adapted to spirallyengage a cable and secure the same to a supporting element in a suitable Heretofore in mounting cables of this general character, great difficulty was had in providing hangers which'would accomplish efliciently various needs in the art. The type lead and the cables are of widely Varying diameter fordifferent installations, and lt was often necessary in laying a cable of this type to hang certain portions of its length in a- "portingvpiate and cable will occur on the horizontal position and other portions in vertical or angularp-ositions. The hangers now in use for the most part comprise various types of hard supports and hard cable engaging elements which Contact the cable on a relatively small'surface, with the result'that the hanger cuts into and destroys the lead sheath 'ofthe cable, especially when used on large and' heavy installations. It wasnecessary heretofore to provide several-different types of hangers in suspending a. single length of cable inasmuch as different problems were 1 involved in supporting a cable when placed in vertical and horizontal positions, and thus no one type would serve foreither position, and it has been further necessary to stock a variety ofsizes to provide for installation of Various sizes of cable.

lit is the purpose of my invention to provide a cable hanger which is capable of installation on a cable of any size and weight with comparative ease, and which is further adapted to suspend a cable in either a horizontal or vertical position and without in any way damaging the lead sheath 1n which the cable is encased.
